Is Evolution Predictable? – ScienceNOW

“Fifty to 100 genes affect whether a worm enters the dauer state. In theory, deletions on any of them could keep worms from becoming dauer larvae. But many of these genes affect several aspects of the animal’s development and physiology, whereas the pheromone receptors simply sense the environment and thus can be lost harmlessly, Bargmann […]

PLoS Pathogens: Selection of Resistant Bacteria at Very Low Antibiotic Concentrations

“These results add another dimension to the evolution of resistance and suggest that the low antibiotic concentrations found in many natural environments are important for enrichment and maintenance of resistance in bacterial populations.” I get a feeling that antibiotics will soon become as archaic as blood-letting. The sooner we deal with the consequences that any […]

Impact of Endofungal Bacteria on Infection Biology, Food Safety, and Drug Development: PLoS Pathogens

“The filamentous mould Rhizopus microsporus is a member of the zygomycetes (lower fungi). While some strains serve as food fermenting fungi, others represent infamous plant pathogens and opportunistic human pathogens. Recently, it was shown that some strains of R. microsporus are associated with symbiotic bacteria. Here, we outline why these organisms are important for human […]
